SPECIFICATION forming part of Letters Patent No. 259,879, dated June 20,1882.

' Application filed April 8, 1882. (No model.)

To all whom it may concern:

Be it known that. I, THOMAS LOWDEN, a citizen of the United States, andresident of Lowell, in the county of Kent and State of Michigan, haveinvented a new and valuable Improvement in Saws; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a perspective view of myimproved saw, and Fig. 2 is a top or plan view of the same.

This invention has relation to spring sawing-machines or machines tofacilitate the use of crosscut-saws; and it consists in the constructionand novel arrangement, in connection with the standards, frame, andC-spring secured to the rear end thereof, of the adjustable lever, itspivot-bolt, and series of hooks for the connecting-rod, the pitman, andthe spiral spring connecting the rear extension of the pitman to thelever, all as hereinafter set forth.

In the accompanying drawings, the letters J J indicate the standardswhich support the main bars L L of the frame. These bars L L areconnected by a cross-bar, K, and by bolts (1., which pass through themiddle block, b, and the rearwardly-extended spring support or rest M.

A designates a strong C-spring which is bolted to the rest M, andcurving forward under the same is provided with an eye, 0, at its frontend. 0 represents the saw-lever, having a series of bolt-holes, d, andback of the same a series of hooks, c.

D is the pivot-pin which connects the-lever to the bars L of the frame,said pivot-pin passing through one of the bolt-holes d.

The spring A is connected to the lever O by means of the connecting-rodB, which engages the eye 0 and one of the hooks c.

To the rear end of the saw Sis pivoted the pitman E,whicl1 connects thesaw to the lower end of the lever O, and the rear end of the pitman isextended at k, and is provided witha rear spring, I, connected to theextension and to the lever 0 above the same, and serving to hold the sawdown to its work and to prevent jumping.

G G indicate the spikes in the front ends of the frame-bars L L, wherebythe machine is attached to the log.

F represents a plate, secured by its front end to the inside of one ofthe bars L and having its rear portion free, forming a catch or rest forthe saw when not in use.

Braces I I serve to hold the main bars and standards of the frame inproper relative position.

The saw is operated by means of the handle P at its end, the saw beingdrawn forward through the log and through the lever 0, extending thespring A, which, reacting, effects the reverse movement of the saw.

The saw may be adjusted lower by passing the pivot-bolt through one ofthe bolt-holes, and the connection B can at the same time be connectedto a corresponding upper hook on the lever.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-- 1. The sawing-machine consisting, in connectionwith the standards and frame, of the C-spring secured to the rear end ofthe frame, the adjustable lever, its pivot bolt, and series of hooks,the connecting-rod between the lever and spring, the pitman, and thespring 0011- necting the rear extension'ofthe pitman to the lever,substantially as specified.

2. In a sawing-machine, the combination, with the main spring A and sawS, of the adjustable saw-lever O and the adjustable rod B, connectingthe main spring to the saw-lever, substantially as specified.

' In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

THOMAS LOWDEN.
